Multi-Coupling Hydraulic Connector for Safe Pull-Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies for hydraulic and pneumatic applications require re-switching a constraint lever to disconnect, risking damage to components during accidental detachment or improper maneuvers, especially when subjected to pulling forces.
Innovation Solution
A connector design with mechanical constraint means that can switch between positions to allow for reciprocal release of parts without re-switching the lever, featuring a groove with contrasting and checking means to prevent damage and ensure safe disconnection, and safety features like a tether to absorb pulling forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the constraint lever is used to mechanically connect and disconnect the movable part and fixed part, then the hydraulic connection can be established and released, but the components are at risk of damage during accidental detachment or improper maneuvers
Solution Approach 1:
The patent introduces a buffering mechanism with a buffer element and buffer spring that absorbs excessive pulling forces before they can damage the hydraulic components. This cushioning system is pre-configured to engage when abnormal forces are applied, protecting the connector assembly from damage during accidental detachment or improper maneuvers.
Solution Approach 2:
The patent introduces an intermediary release mechanism consisting of a release element that can disengage the engaging element from the groove without requiring full lever rotation. This intermediary mechanism allows for safe separation of the movable and fixed parts, preventing direct transmission of damaging forces to the hydraulic components during detachment.
2Ease of operation
If the lever is re-switched to disconnect the hydraulic pipes, then the connector can be separated, but this requires additional operational steps and time
Solution Approach 1:
The patent segments the disconnection operation into two independent functions: the constraint lever for establishing mechanical and hydraulic connection, and a separate release element for rapid disconnection. This segmentation allows the release function to be performed independently without requiring reversal of the constraint lever, significantly reducing disconnection time and operational complexity.
Solution Approach 2:
The patent extracts the disconnection function from the constraint lever mechanism by introducing a separate release element that can independently disengage the engaging element from the groove. This extraction allows the release operation to be performed without manipulating the constraint lever, eliminating the time loss associated with lever re-switching.
3Stability of the object's composition
If the engaging means are firmly engaged in the groove to ensure secure connection, then the connector remains stable under normal conditions, but accidental detachment forces can cause component breakage
Solution Approach 1:
The buffering mechanism with buffer element and buffer spring is pre-configured to absorb excessive pulling forces before they can damage the engaging means or hydraulic components. This cushioning system maintains stable engagement under normal conditions while providing protection against abnormal forces that could cause breakage during accidental detachment.
Solution Approach 2:
The release element acts as an intermediary that can disengage the engaging element from the groove when abnormal forces are detected or when release is intentionally triggered. This intermediary mechanism prevents the transmission of damaging forces to the engaging means and hydraulic components, maintaining both stability during normal operation and protection against excessive forces.
